1200W Common Slot Platinum power supply

This 1200 watt hot-plug unit fits HPE Common Slot bays and delivers platinum-rated efficiency for rack servers and storage arrays. It is built for administrators who need redundant-ready power in a tool-less form factor.

Sustained load efficiency and hot-swap operation

At 94 percent efficiency the supply wastes less energy and generates less heat during continuous operation. The hot-plug design lets technicians replace the module without shutting down the host system.

Single 1200W output for Common Slot bays

The kit provides a single 1200 watt output rated for 100 to 240 volt input at 50 or 60 hertz. Buyers who need multiple redundant units or a different wattage should verify chassis limits before ordering.

Questions about this item

How much heat and fan noise does the 1200 W platinum supply generate when running continuously?

At 94 % efficiency only about six percent of the 1200 W draw becomes waste heat, so the internal fan stays relatively quiet even under sustained load.

What server chassis and backplane must I already have for this Common Slot unit to fit and power up?

It requires an HPE server or storage enclosure with a Common Slot bay and the matching power backplane that accepts hot-plug CS supplies.

Will the 656364-B21 share a load with older Common Slot supplies already installed in my rack?

Yes, the Common Slot design allows mixed-wattage CS supplies to operate together in the same chassis for redundant or combined power.
